uhh ok this is nice…idk why but the boost converter blow up after i finished plugging all together, no polarity reverse or stuff i just plugged and then after 2 secs pshh 💥pow big 💨smoke going off…so yeah interesting🤔, i will try to change the V of the boost to 10V and then if my other boost converter blows up💥 again then it must be a cheap, low quality one that i bought…this project is the most unlucky one i’m working on so far😢…wish me luck🙏. Below photo of almost all plugged(without the boost).
